美国聚合物标准品公司（American Polymer Standards Corporation, APSC）专业从事聚合物分子量分布分析，在分析各种材料例如尼龙，聚氨酯，聚乙烯，聚丙烯，共聚物等具有丰富的经验。分子量分布分析的主要方法有凝胶渗透色谱/尺寸排阻色谱(GPC/SEC)；多角激光光散射(MALLS) 以及气相渗透压法(VPO)。 自1983年起，美国聚合物标准品公司即提供多种和水性聚合物标准品，这些标准品非常适合于仪器校准，聚合物样品的GPC/SEC，MALLS或VPO的分子量测定。
Dextran系蔗糖经肠膜状明串珠菌-1226(Leuconostoc mesenteroides)发酵合成的一种高分子葡萄糖聚合物，是目前的血浆代用品之一。其主要用途为：
